I'm doing the same. I have only had a drink on 2 occasions in the last 10 weeks. First time was Christmas eve, and I thought I'd have just a bit of bucks fizz, and that was fine. I just had 2-3 glasses of 4% stuff.
On Saturday I had a couple of glasses of wine with my friend, then went to the pub and had one pint of cider, and then came back home and had another glass of wine. I only just got over the hangover this lunchtime. I was on painkillers all yesterday, had an early night and had to have more painkillers this morning.
The occasion 10 weeks ago that made me quit was where I had just under one bottle of wine over several hours. I was fine all the next day, then spent the evening being sick, to the point where I got burst blood vessels in my face for a couple of days.
I have always had quite bad hangovers, but they are happening more and more from what I would consider a moderate amount of alcohol. I know many people wouldn't consider almost a bottle of wine as moderate, but it's a lot less than I used to be able to drink.
It's just not worth the after effects, and I find once I start drinking I'm no good at moderating what I drink. Once I get past the 2nd glass I will just keep going.
I'm intending to limit myself to two ciders on NYE but I'm hosting a house party for loads of friends. I've warned them all that any alcohol they bring that's left over, they HAVE to take home with them. Otherwise it's going down the sink. I just have no willpower if it's in the house.
